The presence of tiny hairs, called setae, on the toe pads of some geckos is associated with the ability to adhere to smooth surfaces. This ability allows geckos to climb in areas where many predators cannot. Scientists studying the evolution of setae have identified three closely related species of gecko, only one of which can adhere to smooth surfaces. A model of the evolutionary relatedness between these species is represented in the figure. G. humeralis Can adhere OG. concinnatus Cannot adhere 3 OG. antillensis Which of the following statements is an accurate description of the evolutionary relationships shown in the model?

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.
